At Longmeadow, Monty refreshes a container of overgrown herbs, plants alpines in a pot and revisits the shrub and perennial cuttings he took a few weeks ago. Arit Anderson travels to Kent to meet a designer who is placing sustainability and the environment at the heart of the gardens she designs, and the team discovers a garden in Dorset that has been laid out specifically with scent in mind. There is a look back to 2019 as Frances Tophill visits an allotment on the Isle of Man to meet a grower who uses plants to make cosmetics, and on the Isle of Wight there is a second chance to meet an enthusiast who has filled his garden with daylilies. And there are more viewers’ videos showing what people have been getting up to in their own gardens.
